TYPE-SETTING MACHINE.

SPECIFOATION forming part of Letters Patent No. 640,274, dated January 2, 1900.

`Application filed March 1l, 1899.

T tZZ whom may concern:

Be it known that I, FRANcIs B. CONVERSE,

.i r., a citizen of the United States, residing at Louisville, in the county of Jefferson and State of Kentucky, haveinvented a certain new and useful Improvement in Type Setting Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

The object of the invention is to increase the capacity of type-setting machines, allowing the setting of two fonts of type, as Roman and Italic or Roman and head-letter, without materially increasing the size of the machine or number of parts of the keyboard or ejecting mechanism.

The invention consists, broadly, of a plurality of type-cases and mechanism for ejecting type from either of them combined with mechanism for replacin0F one case by another.

More specifically, the invention consists of two banks of type-cases suitably supported by the arms of pivoted levers, whereby one balances the other, and mechanism such that 5 when the bank of cases in use is moved away from the operative position the other bank is by the same movement brought into this position.

The invention may also be summarized as consisting of the combinations of parts hereinafter specified and definitely enumerated in the claims. 4

In the drawings, Figure l is a side elevation of a type-setting machine embodying my 5 inventiomthe supporting parts and race-plate being broken off. Fig. 2 is a front elevation of the portion of the setter above the keyboard,the front right-hand cases being broken away and the rear cases being partly in sectio tion on a central vertical transverse plane indicated by the line 2 in Fig. 3. Fig. 3 is a vertical section from front to rear through the machine; and Fig. et is a horizontal section on the line il et of Fig. 3 looking down- 5 ward, the ejectonbars at the right-hand end being partially broken away to show the toothed roller beneath.

The same letters of reference designate the same part in each iigure. o Referring to the parts by letters, A represents a suitable keyboard, from the frame Serial No. 708,645. (No model.)

of which rise standards B. These standards carry the horizontal frame B, to which are attached the vertical standards B2, the latter carrying frames which support the type-cases.

The type are ejected from the type-cases which are in operative position by ejectorbars O,which are thrown into action when the fingeiukeys are depressed. This is accomplished by a pair of grooved rollers D and D', which are continuously revolved by the belt D2 in the direction shown by the arrow and by a system of bellcrank levers E, located one beneath each ejector-bar and connected by wires F with the finger-keys. Then a linger-key is depressed, the wire F is drawn down, the bell-crank lever E raises the ejector-bar into engagement with the roller D, and the latter forces the ejectorbar forward, ejecting the lowest type in the case (designated T inliig. 3) from the case onto a ledge g, from which it drops by gravity, foot foremost, into a suitable channel in the race-plate G. As soon as this ejection is completed a notch c on the under side of the ejector-bar comes over the bell-crank lever E, and at the same time a notch c comes under the roller D, and the ejector-bar being thus freed from that roller drops by gravity into engagement with the roller D', which withdraws it until the notch c comes over that roller. Each depression of a iingerkey therefore causes an ejec torbar to advance and shove the lowest type from the case in front of it and then return to its initial position. This much of the construction is old, and no claim is made on it herein.

The cases containing the type are arranged in two sets H and H. In the form shown in the drawings each set consists of four cases and each case has twenty-three channels. Either set is adapted to be substituted for the other, whereby with one keyboard two fonts of type may be set. This opera-tion will now be described.

Each of the sets of cases H and H' is supported in a frame J and J'. Each of these frames consists of a bottom bary', a top bar j', side bars j?, and intermediate vertical bars j, the front frame havingaback plate jt. These frames which contain the cases have extended from their sides near their upper ends the IOO studs 3'5 and js. Pivotally surrounding these studs are the links K and K', which are pivoted at their upper ends to the levers or walking-beams L. These walking-beams are keyed to a shaft M, which is journaled in the standards B2. The studs 7'5 j project beyond the links and carry rollers j, which stand in a suitable guideway, preferably the slot b in the standard B2. This slot is preferably formed in the Y shape shown in the drawings and so proportioned that when one stud is at the upper end of one of the branches the other stud must beat the lower end of the junction. Near the lower end of the frames similar slots b are formed in the standards B2, and into these slots take studs j7j8 on the sides, respectively, of the frames J and J. From the construction described it follows that if the shaft M be turned on its axis one frame will be drawn upward and the other allowed to descend, the full movement putting the upper frame into the position just occupied by the lower. In Fig. 3 the rear frame is shown with its cases in active position. If now the shaft M is turned in the right-hand direction, these cases are drawn upward and rearward and the front cases moved downward and rearward and the latter come at the end of the movement into the eX- act position occupied by the rear cases in the drawings.

The lateral distance between the centers of the upper ends of the Y-slots and the junction portion thereof is such'that when either set of cases is in position the front of the rear frame is substantially in contact with the rear of the front frame. When the parts are changing position, however, there is a larger lateral component to the movement of the links connected with the lower frame, and thus at the beginning of the movement that frame draws away from the upper, and the parts are out of contact. After the middle of the movement has been passed the frames approach and come into contact at the completion of the movement. Thus there is no sliding friction of one frame on the other during the movement, though they are in contact at either end thereof.

The weight of the frames and cases in each of the banks being the same and each set of cases containing generally an average amount of type, the cases approximately balance each other, whereby no great force is required to turn the shaft M. This shaft is turned, preferably, throughthe following mechanism: On the end of the shaftv is a rocker-arm N, which is. connected by a link I) with the bell-crank lever Q, pivoted at the side of the frame and having a handle q within convenient reach of the operator.

is a latch-lever q', which carries a pin q2 under spring-pressure and adapted to pass at either extreme position into a hole r in the arc-shaped bar R, secured to a standard B. Thus when the operator wishes to change the On the side of this handle font of type he simply grasps the handle q, and with it the latch-lever q', and moves the same to the other position.

The type-cases each consist of the back plate s, the side stri ps s', the separating-strips s2, and the bottom s3. The rear cases are put into the frameV H from the rear of the machine, the groove s4 on the under surface of the bottom registering with the rib on the upper surface of the cross-bar j of the frame and the front edges of the sides s and strips s2 engaging with the cover-plate jm, secured to the vertical bars of the frame by the ears j and the cases being held at their upper ends by the buttons ji. The front surface of plate j bears against the back plate j4 of the front frame. The front cases are put into their frame from the front side. For the convenient accomplishment of this I provide a pair of loosely-depending hooks U at the sides of the machine. When the front frame is elevated and its lower end swung forward, as may easily be done by hand, the studs jlpass out of the grooves b2 by reason of the opening b3 and engage with the rear edge of these hooks, and a continuance of the movement elevates the hooks until their ends hook over the studs, and thus hold the frame in the position shown in dotted lines in Fig. l. In

this position if the operators fingers are inallel with the position of the case.

Having described my invention, I claim-- l. In a type-setting machine, two typecases, mechanism for moving one of said cases relatively to the other to permit a common ejector to eject type from either case, in
